In the seminar, we will cover the basics of the theory of abelian varieties (i.e., proper varieties over a field with a group structure). Abelian varieties of dimension 1 are the same as elliptic curves. Studying these subjects will allow us at the same time to practice working with schemes and applying the results of the algebraic geometry courses. If there is enough time at the end, we might look at parameter spaces (so called moduli spaces) for abelian varieties.
